... the engine in Vencer Sarthe operating at lower reeves. You don't get then that high pitched F1 like scream, you get when engine is operating say between 6-8th. reeves. Instead say between 4-6th. reeves it sounds like to be the operating reeve range of the Sarthe. That indicates an engine that could easily produce additional 200bhp. I guess a positive aspect may be that - the Sarthe's engine through being relatively low stressed, could hence bee expected to last longer before an expensive overhaul shall become necessary.
